摘要
根据由相似理论得出的准则关系式及已知的实测数据,对杜波夫斯基公式进行了重大修正,得出了新的半经验炉膛换热计算公式,对我国的2种大容量锅炉及5种典型煤种进行了计算,将本公式计算值与苏联1973年《锅炉机组热力计算标准方法》公式及杜氏公式计算值作了比较,表明本公式能正确符合实际测量结果。
Based on the criterion relations obtained by simular theory and lots of known experimental data, a significant correction for Dubovskii's formula is made and a new semi-experimental formula of heat exchange calculation of boiler furnace obtained. Two types of Chinese boilers and five kinds of typical Chinese coal are calculated. The calculation results obtained by this formula are compared with that by the formula in 《Standard Method of Thermal calculation of Boiler》 of U. R. S in 1973 and by Dubovskii's formula. The results show that this formula can correctly correspond to the actual measurement ones.
